Because of a keynote at useR! in Vienna this summer on psychometrics (and sociometrics, econometrics, educometrics, and so on) in R I have been writing code rather frantically for multidimensional scaling, correspondence analysis, and logit/probit multidimensional IRT models. You can find the code at
http://www.cuddyvalley.org/psychoR or at my homepage http://gifi.stat.ucla.edu Eventually this will be packaged in the appropriate way and documented (dream on, Jan) but it may be useful to some already in its present state. === Jan de Leeuw; Distinguished Professor and Chair, UCLA Department of Statistics; Editor: Journal of Multivariate Analysis, Journal of Statistical Software US mail: 8125 Math Sciences Bldg, Box 951554, Los Angeles, CA 90095-1554 phone (310)-825-9550; fax (310)-206-5658; email: [EMAIL PROTECTED] .mac: jdeleeuw ++++++ aim: deleeuwjan ++++++ skype: j_deleeuw homepages: http://gifi.stat.ucla.edu ++++++ http://www.cuddyvalley.org ------------------------------------------------------------------------ ------------------------- No matter where you go, there you are. --- Buckaroo Banzai http://gifi.stat.ucla.edu/sounds/nomatter.au ______________________________________________ [email protected] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
